The anxiety of loosing a ight
Loosing a ight is likely to be the main concern that travelers’ have
when in an airport, and is likely to be a cause of anxiety and stress to
many people.
Therefore, in order to minimize this anxiety and make all travelers
more condent, airports should provide all relevant ight
information in a clear and perceptible way.
For this, several new ways to communicate information to travelers
are nowadays being used in airports, for e.g. electronic screens,
mobile apps, etc. Nevertheless, audible announcements through
Public Address systems (PA systems) are still likely the preferred
way to communicate the most relevant information to travelers. For
example, when a gate changes or even if a security risk is happening
in a specic section of an airport, this is normally communicated via
an airport’s PA system.
Consequently, achieving high speech intelligibility of an airport’s PA
system is considered extremely important. This is even more relevant
if we think that a considerable number of travelers are likely to be
foreigners and/or non-English natives, i.e. are likely to be people
that will have to understand the message in a foreign language. For
travelers with hearing impairments, high speech intelligibility of an
airport’s PA system is even more relevant.
